IQ System Controller System Shutdown – North America
When the Enphase storage system needs service, installer or homeowner can choose to bypass the
Enphase storage system to connect the home to the grid. The current method of bypassing the Enphase
storage system consists of a few steps, including opening of all the breakers in the IQ System Controller
smart switch, turning off the DC switch on the IQ Battery units, disabling generator – if applicable, turning
the "manual override" toggle in IQ System Controller, and closing back all breakers.
Refer to the label below for the complete instructions on how to initiate manual override and how to exist
manual override. We recommend that you download the label from this link and apply to the IQ System
Controller deadfront, above the manual override section. Please note there are separate manual over ride
instructions for System Controller 1 and 2.
